I installed a simple process where a service task invokes a Java class (AWDocMailConsumerService) at regular time intervals.
i don't use the application activiti-explorer.
I use external web app that invokes Activiti REST services and through which the user enters the values (relative to the user task) in a form.
I use Activiti 5.18.0
The jar containing the Java class and all the required libraries are installed in webapps/activiti-rest/WEB-INF/lib
I use a tomcat 7.0.1 on Windows 64bit environment.
Once I deployed everything and started tomcat, I get randomly the following error:
11:48:29,986 [pool-1-thread-2] ERROR org.activiti.engine.impl.jobexecutor.TimerExecuteNestedActivityJobHandler - exception during

The class code AWDocMailConsumerService runs successfully but in most cases not the first attempt and it may happen that no longer run if the error is repeated for at least 3 consecutive times.
